Boil up plenty of salted water. Preheat the oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer). Dab fillets dry and fry in a large pan in hot oil for 3-4 minutes on each side. Season with salt and pepper and place in an ovenproof dish.
Mix half butter, breadcrumbs, mustard, honey and pepper. Mix in the parmesan. Gently press the mixture onto the fillets. Mix the egg yolks and 1 teaspoon cold water, brush the crust with it. Bake in a hot oven for 10-12 minutes.
Peel and chop the onion and sauté in 40 g of hot butter. Add flour and sauté briefly. Add 500 ml water and stir in vegetable stock. Bring to the boil and simmer for 4-5 minutes.
Cook the pasta in boiling salted water according to the instructions on the packet. Clean and wash the broccoli and divide into small florets. Cook broccoli for the last approx. 3 minutes of pasta cooking time.
Stir cream cheese and frozen herbs into the sauce. Season with salt and pepper. Drain the pasta together with the broccoli, drain and put back into the pot. Stir in the sauce. Take the fillets out of the oven, cut them into slices and serve with the noodles.
